Philadelphia  has become an increasingly popular destination for international travelers. It is in the Eastern time zone, the same as New York and three hours ahead of the West Coast. English is the language spoken and U.S. dollars are the currency. There is an American Express office at 16th Street and John F. Kennedy Boulevard (215/587-2300), where you can cash travelers checks or change money.
The International House  (2701 Chestnut St., 215/287-5125, www.ihousephilly.org ) on the University of Pennsylvania  campus also serves as a great resource for international visitors. It offers information, social and cultural programming, language lessons, and affordable short- and long-term accommodations for students or anyone affiliated with a university.
